Specification of Letters Patent. Application filed. January 26, 1911. Serial No. 604,922;

Patented 0ct. 29,1912.

automatically after it is thrown into action, and which will lubricate the pin, the roller,-

and the bushing simultaneously.

It consists further in the provision of means for regulating the quantity of lubricant discharged into the chain at one time,

and further provides means for maintain-- ing the lubricating device always'i'n proper position for engagement with the chain.

, It consists further in a lubricating device which is adaptedto be actuated and set in operation by the movement of the chain itself, and this takes place regardless of the speed or pitch of the chain.

In the construction shown in the drawings and described herein,- which is a preferable embodiment of my idea, it consists primarily of a supporting member provided with radialarms having-ducts therethrough adapted to register with the duct in the chain pin and also with the duct communieating with the lubricant reservoir, and as the chain moves, these arms are wung by engagement therewith, so that as each arm is discharging the lubricant into the chain, it is being swung, and the succeeding arm'is being positioned for engagement with the succeeding chain The engagement of the chain pin wit the arm will cause the supporting member uponlwhich' the arms are mounted to be moved away from the chain, and this movement \is accommodated by providing a slideway therefor, and resilient means for returning the same to its proper position.

It consists in further parts and their combinations, all of which will be'specifically hereinafter described and set forthin the claims.

Referring tothe drawings which are here to attached and hereby made a part ofv this specification, Figure 1 is a plan view 'ofmy improved lubricating device and a portign of the chain, showing the manner of engagement with the chain; Fig. 2 is a vertical longitudinal section along the line 1-2 of 'Fig. 1. 4

In the ,drawin s' in which the same numeral indicates t e same-part throughout,

K is a base'plate provided with the tongue K, the base plate as here shown having a yoke shape; secured to; the arms of the yoke adjacent to its openend is a bar L secured in place by bolts L Mounted to slide upon the ton e K. on the base plate K is a sup- .porting member. D, which is adapted to reciprocate upon the plate K; mounted upon the rear portion of the plate K is a member K havlng a projection R thereon, and from the supporting member D extends the projection R; these projections are arranged to receive the coiled spring J, and on account of the space between the free ends of the projections, the supporting member -D is capable of the. reciprocating movement above mentioned. Whenthe supporting member D has been moved against the resistance of the spring J hereafter to be described, the resiliency of the spring will cause the same to be moved'forward' again and to assume its normal position. The purpose of this movement will hereafter be set forth.

The supportin member D has a reduced bearing portion thereon, upon which is mounted the collar 0. This collar is provided at intervals with openings into which are screwed the radial arms B, there being four such arms shown in the drawings; at the outer end each arm B is formed with a circular enlargement B having the stem B formed thereon. The enlargement B is adapted to be received by a socket formed of the two members A and F secured togather by the cap screws S; the socket mem- 40 indicates one 65 on the socket member A, hereinbe 60 to register with the duct the socket member A. Through the socket member A the arm Bend the bearin portion D of the supportin member are formed the ducts I, whic ,are adapted to register and form a; continuous assageway theret-hrough when deslred; a col ar member having the cylindrical extension E formed thereon, has also formed thereon the cone shaped receptacle E 5 a lubricant reser- 0 voir 0 is mounted upon the upper end of the cone E and is provided with the ca 0 It is seen that the cylindrical portion is hollowedto form a continuation of the duct I therethrough, communicating with the lubricant reservoir through passageway I, when the plunger H 15 so posltloned as to admit of such. communication. a In the lubricant reservoir is mounted the I plunger plate Y upon the rod Y, the latter 2O aving the threaded portion U at its upper end, and carryin the s rin T com rcssed between the cap 2 and t e p unger p ate Y; the position of the plunger plate in the reservoir is regulated by manipulatinlg the handle N to operate' the traveling nut The plunger H has the stem H mounted upon the member K of the base plate K, the stem H being slotted as shown at H, to receive' the pin M, which is threaded at its upper end and carries the nut M; the p0 sition of the plungerH may be chan ed as desired by loosening the nut Mand s iding the plunger H upon the pin M to any along the slotted 5 with a duct therethrough, having the branch ducts, all being designated by the letter I, leading to the bearing surface between the bushing and the pin and between the roller and bushing. The chain is adapted-to be held again-st lateral displacement'adjacent the lubricating device, in any preferred manner, no arrangement for that purpose being herein shown. The head X of the pin is recessed, as shown, to receive the nipple A ore described, and when the parts are in the osition shown in Fig. 2, the ducts I register continuous passageway, as seen.

and form a The4ducts in the radial arms B are adapted passing through the bearing portion D of the su ortin 4 member and the cylindrical portion il, only after the socket member A has been engaged by the pin head X this engagement causes the supporting member to be moved away point' portion H desired; The 35 collar member E is secured to the bearing F .When the arm is swung from the chain, which operation causes 1 lubricant to pass out into the chain p This registration of the duct through 1 .arm B with the duct leading to the reserv' will be maintained only so long as this gagement with the chain in continues, a it will be seen that it begins before the 21: reaches the position shown in the draw'ir and terminates after the arm hasbeen mov .past the position shown in the drawings.

will be understood that the collar member is perforated only at the proper points permit registration between the duct assi: through the arms-and the duct leading the reservoir, and consequently the lubrica can not pass out of the duct leading throu; the reduced bearing port-ion D until-an a1 has been roperly positioned to effect reg -trat-ion of the ducts. This construction re ders it impossible for the lubricant to discharged at any time exce t when t parts are properly positioned or dischar, into the chain pin.

The device'is set for operation by placii it close enough to the moving chain, so th the face of t e depression A farther aw: from-the ap roachin pin on the chain,

engaged b t e head I? of the pin, it beir understoo that thechainis not movable la erally at this point; the effect of the engag ment of the head X of the moving pin is swivel the socket A upon the bearing B, E thereby'bringing the nipple into the rece formed in the end of the pin, as shown i ig. 2, whereupon the head'ofthe pin is en braced by the depression formed in tl socket member A. The travel of the chai being in a straight line, the effect of ti engagement between the head of the in an the socket member A, is further to s ide tl supporting member D, b transmitting t-l. force throu h the arm away from tt chain, and t is movement of the supportin member D operates to slide the cylinder 13 upon the plunger H. Before the chain pi engages the socket member A, the lubrica' ing device is so positioned that communicz tion exists between the reservoir 0 and th passagewa I through theduct. I, an through t is passageway the lubricant i forced by the lunger plate Y acted upo by the sprin into the continuous assa way I, whic is filled with'the lubricant t the point where it registers with the cor tinuation of the duct through the arm: into the proper pc sition, as hereinafter described, the slidln movement imparted to the sup orting mem ber D by the engagement with the pin, a described, causes the plunger H to force th lubricant into the duct I in the pin, and con sequently through the branch ducts therei1 into the bearings of the roller and the pit The forward movement of the chain, at th same time that it is sliding the'lubricating device away froni-the chain, is also causin the arm B to rotate-on the bearing D", an

when thepin head X has passed out of enga ement with the socket member A, a second arm is left. in proper osition to be engaged-in a similar manner y the recessed head on the succeeding pin. As soon as the engagement between the chain and the socketmemberA has ceased, the sprin 'J, which has been compressed by the sli ing move-- ment of the supporting member D, expandsand moves the whole. device toward the moving chain, so that the succeeding arm is p.0- sitioned properly for 'enga ement with. the recessedheadof the succee ing pin, whereupon the same cycle of o eration is re The plunger Hmay be a just-ably positioned as'described above, thereby locatmg it in the cylindricalportion E tocause a greater or smaller quantity of the lubricant to ass into the chain pin, as desired; it is rea ily seen that if'the plunger H is positioned as shown in Fig. 2, a certain quantity of the lubricant will be directed into the chain pin, whereas, if the plunger should be positionedtoward the right, as shown in Fig. 2, a larger quantity 'of the lubricant would be forced'outagainst the top surface of the lubrlcant, and

the spring exerts a constant pressure thereagainst, tending to force the lubrlcant out into the continuous passageway at all times;

it is apparent that the lubricant/will be thus forced into the passageway when the device is waiting to be engaged by an approaching pin. may be provided upon the collar- G, the number required being determined by the frequency of the occurrence of the pins. Further, when the socket A' is-rotated upon the bearing B, B, the spring G will always operate to return the socket members to their proper positions.

It is seen that I have provided a device which will be actuated by the movement of the' chain itself, and='which in all respects is automatic; the amount of'the-lubricant forced into the bearings can be fixed by properly tensioning the spring T and roperly positioning the plun r' H, an by this means I can also provi e forlubricants for: different degrees of solidity.

Itwill be understood that'my device is intended rimarily for use with a'hard'or rather so 1d lubricant. It is simple in its construction, has no parts which are readily put out of order, is easily manipulated, and

' withal is effective.

I do not desire to confine myself'to the ated."
